Dear all,
It is a pity that some people take any possible negative remark on the sector they work in as unjust criticism. I mentioned overgrazing but I did not mention yak, cattle or goats. Just the term overgrazing already upset Mr. Wangdi. I also did not mention blue sheep or takin. The latter may have upset some nature conservationists.
However, in the areas that I have visited blue sheep are unlikely to be the main cause of overgrazing in cordyceps areas as they tend to graze on the more sparsely vegetated slopes, leaving the open meadows where they are more vulnerable to predators to other grazers. But it is not even clear if overgrazing would have an effect on host plants or the effect could even be positive. I was merely suggesting an intensive study of the plants and animals that are included in the life cycle of Cordyceps sinensis and its host caterpillar and the factors that may affect these
populations.
Harvesting techniques that were observed once in Trashi Yangtse and involved digging up the whole area in which cordyceps was found could also be more destructive. There may be natural enemies or other factors causing a high mortality among the Ghost Moths. Who knows? There may be information in Tibet about possible disappearance of cordyceps from areas where it used to grow. Why are so many Tibetans and Chinese trying to collect cordyceps in Bhutan and Nepal. Maybe it has always been more abundant there, but maybe it has largely disappeared from former habitats in Tibet. I am only speculating and possible some people have more information than I have. More and broader research seems to be required.
so long,
Piet van der Poel
Still in China.

Dear E-foresters,
Thanks for all for the contributions. I come from Department of Livestock
and felt sad to hear the blame for possible damages of plants that hosts
caterpillar or Ghost moth by our cattle/yak/sheep. There is no such
findings and why to guestimate and blame others. Blue sheep population is
also increasing in the alpine meadows or they do not eat host plants.
Instead should find partners for such resource sustainable management and
use.
R&D on harvesting and conservation should go hand in hand to avoid any
mishap of over harvesting which will be very costly for high alpone
dwellers. There is plan to reallot the Tsamdrog to herders by putting in
place of a management plan prepared jointly with herders, Department of
livestock and Department of forest. Research findings on cordyceps or on
caterplillar host plant if any will be useful in the preparation of
grazing resource management plan.
looking forth to hear more on it.
